Answer is: 10.164 grams of iron.

Balanced chemical reaction: 8Fe + S₈ → 8FeS.

m(FeS) = 16.0 g; mass of the compound.

M(FeS) = 87.91 g/mol; molar mass of the compound.

n(FeS) = m(FeS) ÷ M(FeS).

n(FeS) = 16 g ÷ 87.91 g/mol.

n(FeS) = 0.182 mol; amount of substance.

From chemical reaction: n(FeS) : n(Fe) = 8 : 8 (1 : 1).

n(Fe) = 0.182 mol.

m(Fe) = n(Fe) · M(Fe).

m(Fe) = 0.182 mol · 55.845 g/mol.

m(Fe) = 10.164 g.

How is freeze dried ice cream made
ollegr [7]
Freeze drying<span> (or lyophilization) removes water from the ice cream by lowering the </span>air pressure<span> to a point where ice sublimates from a </span>solid<span> to a </span>gas<span>. The ice cream is placed in a </span>vacuum chamber<span> and frozen until the water </span>crystallizes<span>. The air pressure is lowered, creating a partial vacuum, forcing air out of the chamber; next heat is applied, </span>sublimating<span> the ice; finally a freezing coil traps the vaporized water. This process continues for hours, resulting in a freeze-dried ice cream slice. </span>

A student designs an experiment to see the effects exposing a block of ice to sunlight over time. The students makes a hypothesi
jeka94

In this experiment, the experimental group is ice, the independent variable is sunlight while on the other hand, the dependent variable is block of ice.

<h3>What are dependent and independent variables?</h3>

Dependent variable is a type of variable in which a variable whose value depends on another variable while on the other hand, independent variable is a type of variable in which a variable whose value does not depends on another variable. Dependent variable is denoted by X whereas the independent variable is denoted by Y.

So we can conclude that In this experiment, the experimental group is ice, the independent variable is sunlight while on the other hand, the dependent variable is block of ice.
